I have a PAP2 phone adapter connected to a Linksys BEFSX41connected to a Motorola SB5101 modem connected to Earthlink Cable Internet. My problem is my internet IP address messes up causing my internet to stop working. The fix is to go into the router and renew to get a new IP then everything works. Anyone know how to fix this, I am sure it is the Vonage phone adapter, am not sure how to make it work correctly.

your pap2 is doing that? heh, that's pretty impressive since it really doesn't have anything to do with your 'internet ip'need some more details here. apparently when you remove the pap2 everything works fine?
